Patented July 3, 1945 ff STATES PATENT ,"2,379,616j MOLD v: Roberti). Watson, Mclvyleesport," s s l '4 Application June 5, 1942, serial N0..445,9o7 v (orage-,1142 l y. d s claims. This invention relates to improvements in apparatus for the molding andv casting of articles such as billets, ingots; blooms, bars or other-ar- The primary object of this invention is'the provision of molding apparatus primarily adapted for the molding of billets which will' enable the casting of a plurality of readily separable 'billets eirciently and economically Withoutany unnecessary Waste of the molding materiali A further object of this invention yis the'provisionof a'mold apparatus for the molding 'of billets or-ingots in which the molding space iS so e'iiiciently arranged as to eliminate the waste of the Imolding material. Y' e 'l A further object ofthi'sinvention is the provision of a mold made up of a plurality of pieces which `can be readily assembled lor disassembled', the parts of-whic'h are suchas to be readily replaceable so'that shouldany part become damaged,'it Will-not be necessary to replace the entire`mold. 1 f Y A further object of thisfinvention is theprovision of arknockdown mold comprising a plurali-ty of walls which arerelatively connected together so that they can beeiiicie'ntly separated to expose the lentire molded article orarticles.

Other objects and advantages of this invention will be apparent during the coursev of the followingy detailed description.

In the drawings, wherein for the purpose of illustration is shown onlya preterred embodiment of the inventiomthe letter Amay generally designate the improved mold. It consists of side walls B,` 4C, D and E; a bottom wall F and a top Wa11G." 1` w` 'The-object moldedby the improved apparatus is shown at H and consists of'a plurality of billets,vingots, blooms, bars or other articles Il),v Il,`

' |12, 4I3 and Mconnectedtogether and'readily separable from each other. l

.'The'WallsfB, C, D and E are complementary and preferablyof identicalconstruction. The same includes a flat body portion 20 .'of general 'rectangular formation; Projectingv in "right angled relation from the inner 'surface 2| thereof is a separator rib or partition 22 whichv "is preferably ofthe same thickness as one of V'the-*billets il), 11,3 I2,y I3 `or i4. It is disposed inaxial relationupon thebo'dy portion 20, The walls ByC, D andv E are so'connected at their-side margins as to, be. intertting; in l'a relation whichwwillpermit of their securement togetherin an exact relationship. Thusfe'ach Wall is'pr'ovided withside marginal beveled edges 23 and'24'for a portion of the thickness thereof; One'side margin for the restvof the thickness has asurface 25 in right angled relation with th'e inner surface 2| an'd/intersectingthe same'. The other side marginlof the body'20 is offset "at 26 to provide 'a step seat for the inner corner of the adjacent Wall; vThe intertting of thefsi'de in Figure 3 of vthe drawings. I

f 'Ilhisfseat-ZS 'is provided along one sidem'ar- 'ginf'of each side plata* If desired, thelsidemar- Wallsor' plates in this lrelationship is'shownjbest ginsymay be formed otherwise than herein de-A scribed, since the ypurpose of torming'these'side edges thus is to facilitate exact seating'and right angled positioning of the complementary side plates or walls in their assembled relation.

The bottom wall F includes a base portion 30 and upstanding `corner anges 3| at each corner and Palong each side thereof to provide movement limiting means for the interfitting of the side plates B, C, D and E thereagainst.

The top wall G is generally formed the same as the bottom Wall. It has a top wall body 40 with corner ilanges 4I along each side thereof to provide sockets for receiving the corner portions o-f the complementary assembled plates B, C, D and E in the relationship shown in the drawings. The top plate G is formed different from the bottom plate F in respect to a' centrally disposed rectangularly-shaped pouring opening 50, which opens above the space provided by the facing surfaces 6I of the partitions 22. This opening 50 may be as shown in the drawings or formed otherwise. Preferably, the opening 50 has communicating grooves 52 diagonally radiating from the corners thereof and extending over the billet forming cavities 65, 66, 61 and 68 formed at the junctures of the side plates of the' mold; these grooves facilitating not only the pouring of the material in the mold but the complete filing of the mold cavities without air pockets, etc., l.

The arrangement nofthe billet cavitiesv 60, 65,

'66,' s1 and ss is shown in Figure 3 of the draw- All of these cavities are of the same crossL ings. sectional area and the four corner cavities 65-68 `are of the same height.

The cavity BIJ is in` creased in height by reason of the iiller openingv fof the invention or the scope of the claims.

I claim: Y l. Apparatus for the molding `of billets and the s like comprising a plurality of side plates, detach- 50 so that the central billet portion is slightly higher than the corner billets 'lll-I3. i i

The side wall partitions 22 are rounded. at their.. inner corners to define very shallow passageways" 101 bet-Ween the central billet cavity V'lill and each of the corner` cavities 65-68. Thesesmall passageways form vdiagonally disposed connecting webs 80 which connect the corner billets v'III-I3 with the central billet I4, as is 'best shown in Eigure of the drawings. These webs 80 are so slender as to permit of relatively easy fracture thereof, and thus separation of the billets `fromY each other,

As .shown in the drawings, the molding apparatus is` capable of producing live billets of substantially uniform size.

` Means is provided to hold the Vwalls B, C, D and E in their complementary assembled relation. This means may consist of angle brackets 90 and 9| welded along the outer side surfaces ofY each of the -wall plates. In assembled :relation the angle plates 90 and 9| of adjacent mold plates cooperate to receive adjusting bolt means 92 of any approved nature. In this manner the plates ymay be efficiently laterally clamped together.

`The top and bottom plates are provided with means for clamping Vthe same together upon ,the

top and bottom edges of the mold. This means fmay consist of hooks 95 and 96 welded -to the bottom and top plates respectively of the mold apparatus, at opposite sides of the mold apparatus. Rods 91 and 98 may be -detachably connected upon these hooks and adjustably` secured together by means of a turnbuckle'arrangement 99 so that the top andfbottom plates may be clamped securelyv in-placeupon the side walls or plates .of the mold, as shown in Figures land 2 of the drawings. i

it is noted :thatiiiie' billet able top and bottom plates, means to detachably connect rall of said plates together to form a chamber, and means in the chamber partitioning the same into a plurality of billet forming cavities consisting of acentral billet cavity and cornerzbillet cavities relatively separated from each other, all of said cavities having intercommunication along the vertical disposed adjacent edges thereof. f l

.2. VAs an article of `manufacture a mold comprising side walls, a topwall, a bottom wall, said side walls having spaced .partitions rigid therewith intermediate the side margins thereof andprojecting .into the chamber of the mold, said spaced partitions having their innersurfaces facing together in spaced relation toprovide a mold cavity, each of the partitions being spaced lat eachof their side surfaces from the adjacentinside surfaces of the facing. side walls `to denne mold cavities, the :partitions being relatively spacedfrom each other at their most adjacent points to dene .passageways intercommunicating the mold caviiteslast mentioned with the first mentioned mold cavity whereby metal poured into the first mentioned mold cavity will ow uniformly into the other mold cavities andiill the same /at the` same time that the rstmentioned cavity is being filled.V

3. In a folded arrangement of billets, ingots, blooms or like molded articles, the combination of a central billet and` a plurality of billets surrounding the same and'connected therewith -by relatively thin frangible webs, the centralbillet being relatively highenand extending above the top surfaces of the other billets and being connected at .said extension with the top surfaces of the said other billets by means of fracturable web iianges.
